1 Claim. l

This invention relates to hub assemblies for wheels, gears, pulleys, and the like, and more particularly to a hub assembly which is secured against accidental loosening and which may be readily taken apart when desired.

A main object of the invention is the provision of a novel and improved hub assembly for wheels, gears, and the like, which is simple in construction, provides a secure connection to a shaft or axle, and which provides means for pulling the wheel or similar member from the shaft or axle with a minimum amount of labor.

A further object of the invention is to provide an improved hub assembly for securing a wheel, gear or similar member to a keyed shaft or axle, which is sturdy in construction, involves only a few parts and which provides means for quickly removing the wheel or similar member from the shaft or axle without requiring a special wheelpulling implement.

Further objects and advantages of the invention will become apparent from the following description and claims and from the accompanying drawings, wherein:

Figure 1 is a front View of a flanged hub nut employed in the hub assembly of the present invention.

Figure 2 is a side view, partly in cross-section of the hub nut of Figure 1. f

Figure 3 is a vertical cross-sectional view taken through a hub assembly constructed in accor-dance with the present invention, said view being taken on line 3 of Figure 4.

Figure 4 is a fragmentary front elevational view of the hub assembly of Figure 3.

Figure 5 is a vertical cross-sectional view taken through a modined form of hub plate in accordance with the present invention.

Figure 6 is a fron't elevational view of the hub plate of Figure 5.

Referring to the drawings, I I designates the tapered end of a shaft or axle, said end terminating in a threaded stud portion I2. Designated at I3 is a wheel, gear, pulley, or similar member, which is mounted on the shaft end I I and is suitably keyed thereto by a key I4 received in opposing keyways formed in end II and the hub portion of the Wheel member I3. Threaded on stud portion I2 is a nut member I5, which may be of the castellated type, whereby it may be locked to said stud portion by a Cotter-pin I6. Nut member I5 is formed with a flange II which bears on the end of the hub portion of the wheel member I3, as shown in Figure 3.

Designated at I8, I8 are a pair of hub plate 2 segments formed with thickened peripheral portions I9 which bear against the wheel member I3 outwardly of its hub portion and which serve as spacers for the inner portions of the segments, said inner portions bearing on the flange I 'I of the nut member I5. Extending through the wheel member I3 and the thickened peripheral portions I9 of the respective hub plate segments I8, I8 are a plurality of bolt members 2B and threaded on the ends of said bolt members are the cap nuts 2|. The cap nuts ZI cooperate with bolt members 20 to hold the hub plate segments I 8, I8 in overlying relation tothe flange I l of hub nut I5, and prevent the nut from coming off the stud portion I2 in the event that the cotter-pin I6 is lost.

The wheel member is mounted on the shaft by rst engaging its keyway with the key I4 carried in the shaft keyway in the usual manner and forcing it as far as possible manually on the tapered shaft end II. Nut I5 is then threaded on the stud portion I2 and tightened until flange Il has forced the wheel member fully onto said tapered shaft end. The segments I 8, I 8 are then secured on the wheel member in the positions shown in Figures 3 and 4 by means of the bolt members 20 and the cap nuts 2l. The cotterpin I6 may then be inserted through 4the cotterpin opening provided in the end of stud portion I2.

To remove the wheel member I3 from the shaft, the Cotter-pin II is rst removed and nut member I5 is then unthreaded fromstud portion I2.

Flange I'I transmits an outward axial thrust tol the Wheel member through the segments, I8, I8 which loosens the wheel member from the tapered shaft end II and effects the separation of said wheel member from the shaft end without requiring the employment of a special wheel-pulling implement to overcome the frictional force holding the Wheel member on the shaft.

Instead of using separate hub plate segments I 8,I8, a single hub plate member 22 may be employed, as shown in Figures 5 and 6, said single hub plate member having the thickened peripheral portion 23 corresponding to the portions I9 of the segments I8, I8, The inner portion of the single hub plate member 22 overlies the ange I'I of the hub nut I5 in the same manner as described above in connection with the segments I8, I8.

While certain specific embodiments of the hub assembly for wheels, gears, pulleys and the like, have been disclosed in the foregoing description, it will be understood that various modications i 3 within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as deiined by the Scope of the appended claim.

What is claimed is:

A hub assembly comprising a. tapered shaft element formed at its end with a threaded stud portion, a wheel member having a central hub portion fitting on said shaft element, a non-oircular nut member threaded on said stud portion;

said nut member being formedfwith a, iiangev en- 1 gageable with said Wheel member, a plate mem'- ber encircling said nut member and overlying said flange, said nut member projecting externally from said plate member, said platevmember being formed with a thickened peripheral portion, and" means securing said thickened peripheral per-` tion to the wheel member, whereby outward thrust exerted by said flange relative to said shaft element is transmitted through .the plate member to the Wheel member.
